Final answer:
The frequency of the waves is 0.25 Hz, the wavelength is 5.0 m, the speed of the waves is 1.25 m/s, and the amplitude cannot be determined from the given information.
Step-by-step explanation:
To calculate the frequency of the waves, we can use the formula frequency (f) = 1/period (T). Since waves pass the bow of the boat every 4.0 seconds, the period (T) is 4.0 s, therefore the frequency is f = 1 / 4.0 s = 0.25 Hz.
The wavelength of the waves is simply the distance between two crests, which the fisherman has measured to be 5.0 m. Thus, the wavelength (λ) is 5.0 m.
To find the speed of the waves, we can use the formula speed (v) = frequency (f) × wavelength (λ). Therefore, the speed is v = 0.25 Hz × 5.0 m = 1.25 m/s.
The amplitude of a wave is typically measured from the rest position to the crest. However, the fisherman in question has not provided any measurements for amplitude, and thus this cannot be calculated from the given information.
